The first paper is fed by the paper feed roller and the feed roller driven by M101(LT paper feed) via MC101(LT feed MC). The paper feed roller and feed roller touche the paper when SD100 (LT first feed) is ON, feeding the paper to the conveyance roller. Then, SD100 (LT first paper feed) turns OFF to release the paper feed roller and feed roller from the paper. The conveyance roller is also driven by M101, by turning ON MC102 (LT first feed MC), paper is fed to the main body. The related signals are: PS100 (LT top cover open/close detection), PS106 (LT feed), PS107 (LT first feed), and PS110 (LT jam access door open/close detection).

1. Operation

a. First paper feed timing

(1) Start of first paper feed

At predefined interval after the START button is pressed.

(2) Start of second and subsequent papers

When PS106 (LT feed) is turned OFF by the preceding paper.

(3) OFF timing

When the main body M7 (paper exit) turns OFF.

b. Interlock

The power supply line of M101 (LT paper feed) is equipped with MS101 (LT interlock/1) and MS102 (LT interlock/2). When the top cover is opened, MS101 turns OFF, and when the jam access door is opened MS102 turns OFF, thereby cutting off the power supply to M101. Furthermore, the top cover is equipped with PS100 (LT top cover open/close detection) and the jam access door is equipped with PS110 (LT jam access door open/close detection) and when either of these doors is opened during paper feed, the M101 drive signal is turned OFF to stop the paper feed operation.

c. Internal heater

The LCT is equipped with HTR101 (LT internal heater) to protect the paper from humidity. HTR101 is directly controlled by the main body PRCB (printer control board) rather than by the LTDB (LT drive board).

REQ4

When the top cover opens or closes, M100 (LT up/down motor) rotates forward or backward to move the up/down plate up or down. The up/ down plate descends by 120 mm each time SW100 (LT tray down drive) is pressed while the top cover is opened. The related signals are PS100 (LT top cover open/close detection), PS101 (LT lower limit detection), and PS109 (LT upper limit detection).

1. Operation

a. Up/down plate descend timing

(1) ON timing

When the top cover is opened and PS100 (LT top cover open/close detection) is turned OFF, M100 rotates backward to lower the up/down plate. When SW100 (LT tray down drive) turns ON by pressing, M100 rotates backward to move the up/down plate down.

(2) OFF timing

M100 turns OFF at predefined interval after PS100 turns OFF or SW100 turns ON. This in turn lowers the up/down plate by 120 mm.

(3) Others

The up/down plate descends by 120 mm each time SW100 is pressed until PS101 turns ON to indicate the bottom limit of the up/down plate.

M201/M202 (tray up/down/U/L) raises the Up/ down plate/U/L. When SD201/SD202 (sheet feed/U/L) and MC201/MC202 (conveyance/U/L) comes ON, the drive of M203 (PI conveyance) is transmitted and the sheets are fed one by one by paper feed, feed, and double feed prevention rollers. MC203 (registration) controls the drive force transmitted to the conveyance rollers /U/L, which forms a loop for the fed sheet.

The related signals are: PS201/PS206 (PI passage U/L), PS202/PS207 (No sheet/U/L), PS203/PS208 (Sheet setting/U/ L), PS204/PS209 (Tray upper limit/U/L), PS205/ PS210 (Tray lower limit/U/L), PS212 (Sheet size/ L), and VR201/VR202 (Sheet size/U/L).

1. Operation

a. Automatic sheet feeding (online)

(1) When the main body's START button turns ON,

M201/M202 (tray up/down/U/L) are driven in forward, which lifts the Up/down plate/U/L until PS204/PS209 (tray upper limit/U/L) are activated.

(2) Concurrently, while M203 (PI conveyance) is

driven at low speed, SD201/SD202 (sheet feed/ U/L) and MC201/MC202 (conveyance/U/L) come ON and sheets are fed into the FNS stacker.

2 UNIT EXPLANATION

(3) When the last sheet on the Up/down plate/U/L is

fed and PS203/PS208 (sheet setting/U/L) come OFF, the no-sheet-signal is sent to the main body, causing the first feed of main body to stop. After that, when PS202/PS207 (no sheet/U/L) come OFF, M201/M202 (tray up/down/U/L) are driven in reverse, which lowers the Up/down plate/U/L until PS205/PS210 (tray lower limit/U/ L) are activated.

b. Manual sheet feeding (offline)

Only the lower tray is allowed.

(1) When the PI operation panel's START button

turns ON, M202 (tray up/down/L) is driven in forward, which lifts the Up/down plate/L until PS209 (tray upper limit/L) is activated.

(2) Concurrently, while M203 (PI conveyance) is

driven at low speed, SD202 (sheet feed/L) and MC202 (conveyance/L) come ON and all sheets set in the Up/down plate/L fed into the FNS stacker.

(3) The FNS carries out the required finishing pro-

cesses (stapling, three-folding, etc.).

(4) PS207 (no sheet/L) comes OFF, M202 (tray up/

down/L) is driven in reverse, which lowers the sheet tray until PS210 (tray lower limit/L) is activated.

c. Sheet conveyance

When the sheet fed from the paper feed unit at low speed turns PS201/PS206 (PI passage /U/L) ON, M203 (PI conveyance) changes its rotating speed to high-speed. At this time, as MC203 (registration) turns OFF, the sheet is pressed against the conveyance rollers /U/L to form a loop. MC203 turns ON when a specified time has passed since PS201/PS206 turned ON, and the drive force of M203 is transmitted to the conveyance rollers /U/L. This causes the sheet whose bend is corrected by loop formation to be conveyed into FNS. When the sheet turns PS206 OFF, MC203 turns OFF after a specified time. With the same timing, MC203 changes its rotating speed to low-speed and comes into feeding operation for the next sheet.

During the double side copy mode, the up / down movement of the original exit gate determines whether to eject the original, or to feed the original to the reversal section to scan it again. The exit gate drive SD (SD302) turns ON / OFF during the double side copy mode. To scan the back side, the original exit gate goes down to convey the original to the reversal section. When both sides of the original are read, the original exit gate lifts to exit the original to the original exit tray.

Original feed is performed by the pickup roller and original feed roller driven by M301 (original feed). Original conveyance is performed by the original conveyance roller driven by M302. Original is fed when MS301 (cover open / close MS) and PS311 (ADF open / close PS) are turned ON. Each of these features is controlled by PRCB (printer control board) and driven by SCDB (scanner drive board).

EDH-4/EDH-7

1. Operation

a. Pressing original against roller and pre-feed-

ing original

(1) Pre-feeding the first sheet of original

By pressing the Start button, M301 (original feed) rotates backwards at high speed (MC301 (original feed MC) is ON) to raise the original pressing plate. Since M301 rotates backward at high speed, the original feed starts by the action of the pick up roller and the original feed roller. M301 stops when a specified time has passed after the original has turned PS304 (original registration PS/1) ON.

(2) Pre-feeding the second and subsequent origi-

nals When the currently scanned original is conveyed and PS304 (original registration /1) turns OFF during the single side original copy mode, M301 (original feed) rotates backward at high speed (MC301 (original feed MC) is ON), the prefeeding of the next original starts. During the double side original copy mode, M301 rotates backward at high speed after a specified time when the scanning of the back side of the first sheet of original has completed, and the prefeeding of the next original starts. M301 stops after a specified time after the original has turned PS304 ON.

b. Original conveyance operation

When the control signal is received from the main body after the pre-feeding operation of the original has completed, M301 (original feed) rotates forward at high speed (MC301 (original feed MC) is ON). The registration roller rotates and the original is conveyed at high speed. The forward rotation of M301 releases the pressure on the original pressing plate. During the single side original copy, the conveyance switches to low speed when the specified time has passed after PS305 (original registration /2) has turned ON. During the double side original copy, the reverse gate opens and the original passes through the reverse gate to be conveyed to the reversal section at high speed. (For details on reverse and conveyance control, refer to [4] Original Reverse and Conveyance Control.)

c. Scan operation

(1) Single side original copy mode

The low-speed rotation of M302 (original conveyance motor) starts in the same timing as the conveyance procedure described above, and the original is conveyed by the conveyance roller. The scanning starts when the specified time has passed after PS306 (original conveyance) has turned ON.

(2) Double side original copy mode

The back side of the original is scanned first, then the front side. The scanning procedure is the same for both sides. M301 (original feed) rotates backward at high speed (MC301 (original feed MC) is ON), and the original is conveyed from the reversal section to the read section. Then it switches back to low speed when the specified time has passed after PS305 (original registration /2) has turned ON. At the same time, M302 (original conveyance) starts rotating to scan the original. The scanning operation is the same as for the single side original copy.

d. Scanning the last sheet of original

When PS301 (last original) turns OFF while scanning is in progress, currently scanned original is processed as the last original. The prefeed of the original stops, and with PS302 (original setting) turned OFF, the original feed tray is detected as empty. M301 (original feed) and M302 (original conveyance) stop when the specified time has passed after the original has passed through PS303 (original exit) and original ejection has completed.

e. Original skew detection control

PS307 (original skew /F) and PS308 (original skew /R) are provided to detect the inclined leading edge of the original during conveyance. PS307 and PS308 are placed at the front and back of the pre-scan conveyance path and determine the inclination in interval at which the leading edge of the original turns these switches ON. A skewed image caused by original inclination is corrected through image processing and image data is writen.

The original exit gate which switches the original exit path is driven by SD302 (exit gate drive). The reverse gate, which switches the original feed path during double side original copy mode, is driven by SD301 (reverse gate drive). SD303 (pressure roller release) releases the pressure on the original exit reversal roller. Ejection of the original and conveyance to the reversal exit are performed by M302 (original conveyance) which rotates the conveyance roller and original exit roller. M301 (original feed) drives the reversal roller and original exit reversal roller to convey the original to the reversal section. Each of these features is controlled by PRCB (printer control board) and driven by SCDB (scanner drive board).

EDH-4/EDH-7

1. Operation

a. Original ejection operation

During the single side copy mode and when copying the front side in the double side copy mode, the original exit gate lifts upward because SD302 (exit gate drive SD) is turned OFF. Therefore, scanned original is ejected to the original exit tray by the action of the original exit roller. PS303 (original exit PS) detects the original ejection.

b. Reversal operation for double side original

copy

2 UNIT EXPLANATION

(1) The first sheet of original

When PS304 (original registration /1) turns ON and pre-feed of the original has completed, SD301 (reverse gate drive) receives a signal from the main body and turns ON to open the reverse gate. M301 (original feed) rotates forward (MC301 (original feed MC) is ON), and the registration roller, reversal roller, and original exit reversal roller convey the original to the reversal section at high speed, passing through the reverse gate. M301 stops when a specified time has passed after PS304 has detected the trailing edge of the original. (The original is conveyed to the reversal section until the trailing edge crosses over the reverse gate.) During this time, SD301 turns OFF and the reverse gate closes.

(2) Second and subsequent original

When PS305 (original registration /2) detects the trailing edge of the front side of the first original, SD301 (reverse gate drive) turns ON to open the reverse gate.The second and subsequent originals are thus conveyed to the reversal section in the same manner as the first original.

c. Feeding the back side

When the reversal operation for the double side copy mode described above has completed, high speed backward rotation of M301 (original feed) (MC301 (original feed MC) is OFF) conveys the original to the read section by the action of the reversal roller and the original exit reversal roller. When M301 rotates backward, SD302 (exit gate drive) turns ON to lower the original exit gate, and the original exit path switches from the original exit tray to the reversal exit. When the specified time has passed since PS305 (original registration /2) is turned ON by detecting the leading edge of the original, SD303 (pressure roller release SD) turns ON temporarily accord-

ing to the original size. By SD303’s turning ON, the pressure on the original exit reversal roller is released. This enables the leading edge and the trailing edge of the original to pass each other. When a specified time has passed since the back side of the original starts to be scanned, SD303 turns OFF, at the same time, M301 has been switched to low speed forward rotation (MC301 is OFF). The original exit reversal roller rotates in the reverse direction, and the original is conveyed to the reversal exit again. As soon as scanning of the back side of the original has completed, SD302 turns OFF, and after the predefined time, M301 is switched to high speed rotation. It stops after the specified interval.

d. Feeding the front side of the original

The original which is conveyed to the reversal section is conveyed to the read section again in order to scan the front side. Since SD302 (exit gate drive) is OFF, the scanned original is ejected to the original exit tray.

The size of the original placed in the original feed tray is detected by PS309 (original size /2), PS310 (original size /1), and VR301 (original size VR). Each of these features is controlled by PRCB (printer control board) and driven by SCDB (scanner drive board).

1. Operation

a. Normal copy mode

PRCB detects the original size from the combination of the following signals:

(1) Drum axis direction size detection

A guide plate is connected to VR301 (original size VR) and the resistance value varies with the position of the guide plate. This is used to determine the vertical dimension of the original.

(2) Original feed direction size detection

The horizontal dimension of the original is detected with the ON/OFF combination of PS309 (original size /2) and PS310 (original size PS/1).

b. Mixed / Z fold copy mode original size detec-

tion

Size detection during mixed and Z fold copy modes are performed as follows:

(1) Drum axis direction size detection

The vertical dimension of the largest original is determined by the position of the guide plate.

(2) Original feed direction size detection

The ON interval of PS304 (original registration /

1) after the original passes the registration roller is used to determine the horizontal dimension of each original.

(3) Original feed direction size detection operation

When the original is fed from the registration roller, in single side original copy mode(when AMS is not used) and double side original copy mode, the conveyance path of original is same as normal conveyance path. In single side original copy mode (when AMS is used) and Z fold copy mode, the conveyance path of original is same as that in double side original copy mode, passing the reverse gate and reverse section. In each case, the ON interval of PS304 (original registration /1) is measured and used to detect the length of the original. In single side original copy mode (when AMS is used), the original is not read before magnification rate is decided. Therefore, the conveyance path of original is same as that in duble side original copy mode, so that PS304 detects the length of the original. In Z fold original copy mode, the length of the first original is detected.
